To secure national future competitiveness, the Korean government announced the 『National Ultra-High Performance Computing (HPC) Innovation Strategy (2021.5.28.)』 and set three innovation strategy goals throughout establishing an innovation ecosystem. This study presented a heterogenous data-based strategic support framework that allowed to understand both the current status of domestic & foreign R&D areas and domestic industrial economy areas in terms of strategic fields related to ultra-high performance computing, and the empirical research was conducted in the life science and public health area. The HPC innovation ecosystem platform based on the connection of heterogeneous data (domestic R&D project-technology-industry-overseas R&D project) presented in this study provided useful and essential information that allowed establishing a specific action plan for the national HPC innovation strategy and contributing to vitalizing the innovation ecosystem. Since the evidence-based policy assumes that a more reasonable consensus is reached through a non-biased decision- making process among stakeholders, the proposed platform may contribute to enhancing policy momentum by increasing legitimacy and trust of planning of the national HPC strategy.

계산 그리드는 대형 컴퓨팅 자원을 필요로 하는 기관들이 계산 자원이나 저장 공간등을 공유함으로써 자원의 이용 효율을 높이고 사용자들에게 보다 다양한 컴퓨팅 서비스를 지원하는 것이 목적이다. 그러나, 컴퓨팅 자원을 많은 수의 사용자 커뮤니티내에서 공유하기 위해서는 자원의 사용과 관련된 어카운팅 정보를 사용자별로 정확하게 수집함으로써 자원의 사용 정책 등에 반영하여야 한다. 그러나, 기존의 어카운팅 방법으로는 그리드상의 수많은 자원들을 효율적으로 관리하기 어렵다. 본 연구에서는 그리드 환경에서 사용자 어카운팅을 구현할 수 있도록 계산 그리드의 클러스터를 기반으로 한 사용자 환경을 설계하였다. 본 연구에서 설계된 시스템은 사용자들이 동일한 자원을 이용할 때 서로 충돌되지 않고, 각자 독립된 접근 영역 안에서 자원을 이용할 수 있게 함으로써 사용자 어카운팅을 간편하게 만들어 준다는 특징이 있다.

For national industrial development in the Fourth Industrial Revolution, it is necessary to provide researchers with appropriate job information. This can be achieved by interconnecting the National Science and Technology Standard Classification System used for management of research activity with the Korean Employment Classification of Occupations used for job information management. In the present study, an automatic linkage model of classification systems is introduced based on a pre-trained language model for interconnecting science and technology information with job information. We propose for the first time an automatic model for linkage of classification systems. Our model effectively maps similar classes between the National Science & Technology Standard Classification System and Korean Employment Classification of Occupations. Moreover, the model increases interconnection performance by considering hierarchical features of classification systems. Experimental results show that precision and recall of the proposed model are about 0.82 and 0.84, respectively.

This paper introduces an online experiment environment based on a computational science platform that can be used for various purposes ranging from basic education to quantum chemistry and professional quantum chemistry research. The simulation environment was constructed using a simulation workbench and simulation workflow, which are execution environment services of Science App provided by the computational science platform. We developed an environment in which learners can learn independently without an instructor by selecting experiment topics that can be used in various areas of chemistry, and offering the learning materials of the topics in a form of e-learning content that includes theory and simulation exercises. To verify the superiority of the proposed system, it was compared with WebMO, a state-of-the-art web-based quantum chemistry simulation service.

Benchmarking is a process used in a lot of companies and public institutions because it is considered to be a practical tool for management innovation. However, it is hard to find out the development of systematic methods and applied cases for benchmarking on information services environment. This study tried to apply the benchmarking process to information distribution environment. This study examined the basic definition and standard process of benchmarking, and then conducted benchmarking plan to innovate tasks of database construction for information services at KISTI.
